Subject: Re: Long division

I have two examples of long division at the following web sites. http://members.aol.com/loydlin3/Ldivide.jpg http://members.aol.com/loydlin3/ldivide4.jpg I usually first approach division with something like this" 17 divided by 5: ***** ***** ***** ** By grouping into fives, it is easy to see that the answer is 3 and remainder 2. Some people use beans and paper plates to demonstrate this. Then, you should realize that division is just repeated subtraction. Thus How many times can we subtract 5 from 17? 17 -5 ---- 12 (1 subtraction) -5 ---- 7 (two subtractions) -5 --- (3 subtractions) 2 Remainder is two The answer is 3 with a remainder of 2. Hope this helps. Keep up the good work. Tutoring is one of the best ways to understand math.
